Using the Sloan Digital Sky Survey (SDSS) data release 4 (DR 4), we investigate the spatial distribution of low and high surface brightness galaxies (LSBGs and HSBGs, respectively). In particular, we focus our attention on the influence of interactions between galaxies on the star formation strength in the redshift range 0.01 < z < 0.1. With cylinder counts and projected distance to the first and fifth nearest neighbor as environment tracers, we find that LSBGs tend to have a lack of companions compared to HSBGs at small scales (
